The only valid way to do catch the hangup in Studio/VxmlServer is using an End Of Call java class that checks how the call ended, and if it was a hangup, simulates what the CVP_Subdialog_Return does. The Java code below does this. It looks for session variables return0, return1, return2, return3 and returns them to ICM. In ICM, they'll show up in the Termination Variable table in the FromExtVXML array entries if you've configured these variable as Persistent.

You will have to compile this java and then configure the Studio app (Project / Properties / Call Studio / End Point Settings / End of Call - Class: EndClassSubRet
And you'll have to have the info in Session variables return0,1,2,3 (or modify the java to grab the session variables that you care about).

The easiest thing to do is attach an EndClass to your application. This custom class will ALWAYS be called, even if the caller hangs up. Create a session variable in the start of the Application (use an App Modifier node) and initialize it. If your caller finishes the app correctly, you can set the variable to something else.

So the end class knows if the caller hung up – because the session var has the initial value. Write something suitable in the app log, something that the CVP Reporting server can find. I don’t know that server – never used it, don’t need it, not paying $20k for it.

Geoff

The above post useful me too

Thanks Janine and Geoff.

Phani (Karthik), have you changed your forum name? This is Pedro's thread, please respect that and stay on the topic specific to this thread.


Janine,

I've seen a similar code sample before, I'm assuming that code overwrites whatever you have in the SubDialogeReturn element in Studio correct? (also assuming this app does not end in an app transfer or something other than a SubDialogReturn). Is there a way to populate directly to the PVs? I am just curious as to where the constraint lives that allows us to only use Caller_Input and FromExtVXML array.

Otherwise Pedro, you'll have to use the AddToLog method against the session API in the custom java that Janine posted to populate to the CVP reporting logs.. you'll find whatever you place in the AddToLog method in the VXML_Custom table in CVP Reporting. Or do as Geoff does and use come custom Java to write anywhere else.

Just to add. If you need more details, the CallEnd Action is very well described in Chapter 5.

Hi Ryan,

I didn't write that end class java from scratch, I got it from the post you mention. Can't remember who posted it, maybe Paul?

The End of Call java class executes no matter how the call ends. But, the java I posted checks if the ended with 'hangup', and only continues in that case. If the caller hangs up, the call flow does not execute the CVP Subdialog Return, so no worries about overwriting it. And conversely, if the call goes thru the CVP Subdialog Return, then the caller didn't hang up. So, no need to worry.

I know of no way to populate the PVs directly. When returning data from VxmlServer one can only populate caller_input, FromExtVXML[0],...[3]. It must be written into the IVR Service or ICM Service code on the Call Server. And, if the caller hangs up, the ICM script ends immediately, so the best you can do is return data that populates the CallTermination Variable table. One might be able to create a session variable in the End of Call java class, assign it the data, and have it show up in the Reporting Server. I haven't tested to see if variables created in End of Call java would make it to the reporting server, but I don't see why not. But, this doesn't address the PV problem.

Maybe Paul Tindall could file that as an enhancement request.

Ryan,
The code will not overwrite the subdialog return at all. These are two separate things. I have used this class to log certain things to database etc. This is more on the CVP side. While subdialog return typically returns your vals to ICM.
Also you can create end class that could write something to reporting server.

Great info. Thanks Janine! I am currently writing to the reporting server on an OnEndCall class just using the AddToLog method, so that is definitely possible. The point of only being able to populate to TCD is a great one, wouldn't have found that out until I tried this. Thanks!

 
Janine,
 
Yes, the original was an example I posted specifically in response to getting hangup indication and data back to ICM.  Unfortunately, further script processing doesn't happen once the final response from CVP gets back to ICM so it's not possible to move data from the ECCs to PVs; that would definitely require a code change.
 
Paul

Rakesh Ameta and other guys
 
Thanks for all samples
 
1 - The big question is after created this class inside my properties project we load on my endppoint Settings?
Properties-->CallStudio-->EndPointSettings-->On Application End
After that we use the (ADD...) button
 
2 - If the system Identify Hang-up i need record the 3 Session Variables (Created on my CISCO CVP application) on this database "SicrediCiscoReports" using this quey showed below.
 
I not so good im Java could you send a new sample with more details using this Database and this Query?
 
JNDI NAME : SicrediCiscoReports
 
QUERY:
INSERT INTO IVRDATA VALUES(
'{Data.Session.s_DataIVR1}'
'{Data.Session.s_DataIVR2}'
'{Data.Session.s_DataIVR3}'
 )
 
3 - Rakesh I do not need to know where and which element in the occors Hangup, the more it can be very helpful too for me.
Today I need to know the piece of the application that he own.(it belongs) Because this my intuite is use only variables
Could you explain your example?
Imagine I have a Menu Element called 'Car Menu', how could I use it on your exemplo below?
 
String strTraversedElementPath= data.getElementHistory();// the element
detail where the call was hanged up
Sorry about a lot of questions Thanks for all.
